• Visual C# Help: Slow Launch application at first run after each reboot

  Hi, I've developed an application (only one screen, not too big,published size is about 4MB) It runs expected. The problem I'm facing is that for a given PC, it takes quite long (1-2minutes) to launch this program. The screen waits at the Launching Application message "Verifying application requirements. This may take a few moments". This occurs only at the FIRST launch after EACH REBOOT. Subsequent launching of the program only takes a fraction of seconds. I don't understand why it happens. Hope someone can give me insights. Thanks! best regards, jackLing Hi, Thanks for your reply again. I get what you mean. I have published my application to a shared folder then run ...Show All

• Visual C++ static const member variable initialization

  Hi, I want to initialize a member variable of a class by calling RegisterWindowMessage and i want to keep this variable as static so that this variable is initialized only once during the execution of the program. When i declare the variable as static, i am getting an error which says that only const static variables can be initialized within a class. When i make the variable as static const, i get the following error - Error 11 error C2057: expected constant expression I think this is because the value i am assigning to the variable is the value which the function RegisterWindowMessage will return and this will not be a const value. Could anyone please suggest a way out of this. Thanks in Anticipation, With regards, ...Show All

• Visual Basic Superconstructors?

  What's the general syntax for using inheritance in VB Say I've got ClassSuper and ClassSub, ClassSub inherits ClassSuper. How do you access the super constructor How do you access values in the super class Thank ya, exactly what I needed. And just to make sure, MyBase always goes up one level, right So if I had SuperClass, SubClass and SubSubClass, to access SuperClass's constructor you'd use MyBase.MyBase.New() ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Runtime model loading

  I am trying to make a level editor with XNA. Unfortunately, I've run into a little snag. I need to load a model from a user chosen location, but as far as i know models need to be first loaded into the programming solution before they can be loaded through the content manager. Is there anyway to do this at runtime fora model thats not part of the solution As long as you can get the models into the .xnb format using MSBuild or VS on the back end, your app should be able to load them at run time. You need to derive from ContentManager and override OpenStream to read assets not stored in the local file system. Won't work on XBox, though. ...Show All

• Visual C# Help on creating a generic singleton class

  I am on the process of creating a generic class for the singleton pattern. My implementation as follows: public class Singleton<T> where T : new() { public static T getInstance() { if (this_ == null) this_ = new T(); return this_; } private static T this_; } Sample use would be: Singleton<Logger>.getInstance().someMethodHere(); The problem with this implementation is that the target class that would be converted into a singleton must have a public constructor, which is in the first place I am preventing it. I have implemented a simliar approach in C++, however I've used a "friend" class that sould also be declared on the user class. Please advice. Thanks. (BTW, th ...Show All

  Hello All, I know all about the alpha blend and all that great jazz.. I can create sprites with transparency pre defined in them with no problem. The problem is what if i want to change the transparency of the hole sprite on the fly in XNA say for partical effects as fire and water... I cant seem to find a property to allow me to do this such as_sprite1.transparency = 69 is it possible to do this in XNA Game studio..

• Smart Device Development GPRS Connect at Startup

  Hi again (again), Last question, I promise. I'm looking to start the GPS up wen the device starts. I don't mind changing hte registry for this, or doing it programatically. All the stuff I have found is either for C#, or the registry info doesn't exist in my phone. Once again, any help would be very appreciated. Cheers, Dan. haha, I had that, but it was throwing errors. I realised later why, but never put it back in, thinking the way I created the variable would take care of the size parameter automagically. Anyways, I added that in, and it still didn't solve the problem. I didn't bother checking the HRESULT cause if it didn't work, the errors for HRESULT didn't seem like they'd be much ...Show All

• Visual Studio Express Editions Compiling error, does not recognise "Windows"

  You're all probably going to think this is an absolutely stupid question, but I keep getting an error with words like "Windows" and "Button". I'm littoraly just starting out at programming and am using the "Sams Teach Yourself in 24 Hours" book for C#. The second program in there is the one that's giving me trouble. We're told to just type straight in, and the Microsoft compiler is one they recommend, so I would have thought it would work fine. The code is: using System; using System.Windows.Forms; namespace HelloWin { public class MyForm : Form { private TextBox txtEnter; private Label lblDisplay; private Button btnOk; public MyForm() { this.txtEnter = new TextBox(); this.l ...Show All

• Visual Studio Team System Spurious AvoidUnnecessaryStringCreation

  Using a switch statement containing a call to String.ToUpper() as the source expression results in (what I think is) a spurious AvoidUnnecessaryStringCreation warning. Example: string foo = "test" ; switch (foo.ToUpper()) { case "FOO" : break ; case "BAR" : break ; case "TEST" : break ; default : break ; } This code snippet results in the following IL: .locals init ( [ 0 ] string text1 , [ 1 ] string text2 ) L_0000: nop L_0001: ldstr "test" L_0006: stloc.0 L_0007: ldloc.0 L_0008: callvirt instance string string :: ToUpper () L_000d: stloc.1 L_000e: ldloc.1 L_000f: brfalse.s L_0040 L_0011: ld ...Show All
